Transcription

1 The CEOS Ocean Vector Wind Constellation: Current Status and Challenges Stan Wilson, NOAA; Hans Bonekamp, EUMETSAT; and B.S. Gohil, ISRO Co Chairs International OVW Science Team Meeting Barcelona May 2010

2 What is CEOS and the OVW Constellation? The Committee on Earth Observation Satellites, CEOS, is a voluntary international forum of 29 space agencies & 19 associated organizations CEOS is planning the space arm of GEOSS The OVW Constellation is a group within CEOS that includes representatives of some but not all agencies involved in scatterometry CEOS provides an opportunity for the OVW Constellation to promote global scatterometer missions i

3 What does the CEOSOVWConstellationOVW Constellation do? Pursues timely & free data access in support of the public good To provide opportunity for all to benefit Facilitates cal/val for each scatterometer To provide confidence in observations Promotes use of OVW, particularly for nonspecialist st operational o a users, s, to strengthen e advocacy base To provide sustained support for future p pp f f scatterometry

4 Pursues Timely & Free Data Access This has not been, is not and/or will not be an issue with: NASA QuikSCAT EUMETSAT MetOp with ASCAT and planned Post EPS NOAA proposed DFS on JAXA GCOM W2 & W3 This is currently being addressed with: ISRO Oceansat 2 with OSCAT This remains an issue with: SOA/CNSA HY 2A launch 2011 SOA/CNSA/CNES CFOSat launch 2013 RosHydroMet/RosCosmos o oscos Meteor M3 proposed poposed2014 CMA DFS on FY 3 proposed 2016

6 Facilitates Cal/Val for each Scatterometer Collaborators working to supportisro on Oceansat 2 OSCAT cal/val include: NOAA, NASA, KNMI, ECMWF, UK Met Office, Meteo France, CSIC (Spain), IFREMER NOAA & EUMETSAT are discussing with ISRO how they can help support timely access to OSCAT data, once the commissioning phase has beencompletedand theoperational phase begins

7 Promotes the use of OVW, particularly for non specialist, operational users Asan exampleof non specialistoperationaloperational users Most developing country marine forecast centers with responsibility for high seas forecasting in GMDSS MetAreas are not routinely using OVW (and altimeter derived significant wave height) in their operational analyses, warnings and forecasts today GMDSS Gl b l M i i Di d S f S f h WMO GMDSS = Global Maritime Distress and Safety System of the WMO and International Maritime Organization

8 GMDSS Met Area High-Seas Operational Forecast Responsibility Data routinely used in operational forecasts? If so, how are they accessed?

9 Approach If two of the most easily understood satellite products relating to the ocean surface are: Ocean Vector Winds (OVW) from scatterometers Significant Wave Height (SWH) from altimeters And if two of the most important products required by a marine forecaster for a surface analysis are: SVW wind speed and direction SWH or sea state Why aren t these centers using OVW and SWH products routinely in operational high seas forecasting today? Depending on what we find, are there any lessons to be learned? 9

10 Initial Training Course Use of Satellite Wind & Wave Observations for Marine Forecasting Co organized by NOAA and EUMETSAT on behalf of the CEOS OVW & OST Constellations and in conjunction with the WMO Space Program. Hosted by the IOC Office for the IODE, with support from the Flanders Government, Oostende, Belgium, December

12 Basic Questions Facing an Operational Forecaster How do I know what observations are available from multiple satellites? How do I get access to those observations? A single point of access for OVW & SWH How do I integrate those observations within ihi my own analysis/forecast system? How do I use those observations in my operational forecasts? Common analysis/display system 12

13 Single Point of Access Single point of access one stop shopping for SWH? Only one set of procedures needed for the user A common operational product could be available in a single self describing, hardware independent format Products could be packaged specific to each area of interest to offer a very low data rate Both graphic display and digital products could be available Each new source could be easily incorporated into service without any involvement on the part of the users 13

14 Local Interfacing Interface with local operational analysis/display system Argentina SMN MESSIR VISION moving to GEMPAK/N AWIPS Brazil MMS GEMPAK/N AWIPS Brazil INPE GRADS South Africa NINJO Work Station Currently lacking this capability Chile considering GEMPAK/N AWIPS Fiji suggest checking with Australian BoM & Met NZ 14

15 Planning for Next Training Course Developa single point of accessforusein of for course using QuikSCAT and ASCAT data for testing Wait for OSCAT data to become available for operational use and then provide it, together with ASCAT data, via the single point of access If new funding can be obtained, hold it in South America to maximize local participation Otherwise hold it again at the IOC facility in Oostende 15

16 Challenges to the OVW Constellation Canwe convince all spaceagencies agencies toprovide timely, free access to their data? For non specialist users (especially operational): Can we agree on a single, inter calibrated C band ASCAT and Ku band QuikSCAT & OSCAT global data set to provide the common product(s)? Can we provide a global data base from which a given user canobtaintimelyaccess timely access tothecommonthe product(s) in a common format(s) corresponding to his area and time of interest?
